Wastewater re-use systems

Abstract

A wastewater reuse system has a wastewater treatment system connected to a dwelling for receiving wastewater therefrom. The wastewater treatment system has a pump tank with an outlet that can be connected to a central wastewater collection system and/or a re-use recipient of treated wastewater such as an irrigation system.

What is claimed is: 
     
       1. A wastewater reuse system operatively connectable to a dwelling for humans, said dwelling being located at a site, said reuse system comprising:
 a pretreatment tank connectable to said dwelling to receive black water comprising human waste solids from said dwelling and allowing settling of said solids in said black water to produce an at least partially clarified black water; 
 a holding tank displaced from said pretreatment tank for receiving said at least partially clarified black water from said pretreatment tank; 
 a transfer line from said holding tank, said transfer line being operable to be connected to a sewage line forming part of a central wastewater treatment system; 
 a drip irrigation system on said site, said drip irrigation system being the sole method of disposing of said partially clarified black water on site, there being no aerobic wastewater treatment used; and 
 a pump connected to said holding tank and selectively operable for pumping said at least partially clarified black water from said holding tank to said drip irrigation system. 
 
     
     
       2. The wastewater reuse system of  claim 1 , wherein there is a filter between said pump and said drip irrigation system. 
     
     
       3. The wastewater reuse system of  claim 1 , wherein said transfer line comprises a gravity flow line. 
     
     
       4. The wastewater reuse system of  claim 1 , wherein said pretreatment tank is free of any filter media.
